Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Friends, i would like to know something. In the electric start of my passion pro, if we press the button start, what actually happens? All i know is, the starter motor rotates and it tends to rotate the fly wheel, followed by the 4 strokes and the spark. Kindly correct me if i am wrong. I read in this thread earlier that there is also responsibility for the excitor coil for the starting of the bike. What job does the excitor coil perform?

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

1 . Yes its acceptable in city conditions , but could have been more

2. Nope not needed , the rubber damps vibrations of rear sprocket and kinda fixes rear sprocket to wheel if it wears , rear sprocket will have play.

3. ask , anl are preferred brands, asbestos ones have better bite but are carcinogenic.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Excitor coil's function is to STEPUP voltage from 12 V to hundreds of volt required at plug

If it stops working you will have poor or no spark at plug as it can no longer step up voltage from battery

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

I'm bit confused on models. Pollution model/Y2K model means the post 2000 models with less pollution?

@ Sibun:

Could you Pl. brief us the Pros/Cons of each of the carbs w.r.t Performance v/s Fuel Efficiency.

Are these Carbs interchangeable for one another.

Welcome to the forum Suresh.
There are only two compression rings that should have 0.2 mm of cleareance. Not more than 0.5 mm max.
Third one is oil ring, no need to check clearence of that.
For dowl pins, there are 4 dowel pins used between block & head. Two pins are placed between block and chamber, if u look from the front then one dowel placed in top right stud and second just opposite of that in bottom left stud. Followed by same position for remaining two dowel pins in between head & block.
In addition to this there is one collor used in between head & block. The collor holds the head oil o-ring in the bottom right stud. The engine oil passess thru that stud when oil pump push it. It went to head and then flows back from the bigger hole/passage in the bottom (you must have seen that). That collor is very important to be there, if not installed or incorrectly installed then engine oil will get into cumbustion and bike will smoke.

There are few more dowels used in other areas of engine that not worth including it as its not pertinent towards your qwery.

Your bike doesn't have excitor coil. The bikes which have AC cdi are powered by excitor coil in stator which produce upto 55 volts. Therefore these bike runs without battery as the source of energy is from excitor. If excitor fails bike will not start. CDI then hold that power into its capacitors which then released to ignition coil after it receives signal from pulsar coil, the pulsar coil send signal when piston is at compression stroke. The power then released to the ignition coil which converts that upto 15000 volts and then yelds spark in the spark plug.

Your bike have DC CDI which powered by battery, therefore bike doesn't start after removing battery. It doesn't had excitor coil which leads to more space in stator and more poles which in turn given better lighting at lower rpm.

"More mods coming soon" when it will come soon man? Its been two months ago I'm waiting for it!!

Again when??
Man previously u stated that, feeling of posting has gone from the day I've stopped being active, but now if i am back after listening your words.
I feel like u have now stopped being active.
Hope u hear from you soon, the updates!!!

[MENTION=53807]paul.1911[/MENTION]- Good explanation to the queries [MENTION=43108]shoeb2015[/MENTION]- Where are you. Have called me a lot regarding his splendor problem and now his problem have been solved. But no updates and all from you. Man update something so that other members can know a lot from you.Carburettors:-As i had posted the jet and needle sizes difference in previous post now i am posting the difference in both the carb. The pre y2k models had smaller venturi size. The venturi size used were 16 mm as used in pleasure, activa and all.The post y2k model had bigger venturi size. The venturi size is 18 mm.Due to changes in length of silencer and introduction in more baffles precisely four extra in the silencer the carb was changed. For making the breathing easier 18 mm venturi was used and the jet sizes were changed. Since the power an torque increased bikes were made more tall geared. Across the spectrum two teeths in rear sprocket was dropped in all models from their pre y2k models.And for swapping, no you cannot swap the pre y2k models carb with post y2k or vice versa.

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Hmm.... Then i should try to find a 19 or 20 mm carburetor. We are trying to milk a bit more power from the small engine as the owner is not very happy with the overtaking ability of the bike.

For the last 2 days, when i type xbhp.com, the website was blocked and also forbidden. I dialled a lot of times and the result was the same. I was totally pissed off, because in the xbhp history, i read that somewhere around in 2005, the forum's server got failed and all the data was lost. Phew.!! just now i am relieved. I thought i would miss you people permanently. Good heavens, the website is working fine now and i am not going to miss any one of you

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Amen to that my friend!

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Hi ,

Even i own a passion pro 2009 model , The carb is a TPS model , the Cdi gets its power from battery and the Regulator rectifier , few days back My battery went down completely . I removed the battery , eventhough i was able to start the bike through kick , the only noticeable change was performance drop .

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Thank you sir. Now i understand. CDI (capacitor discharge ignition) enhances the spark plug to produce spark. Right? My bike has DC powered CDI. So, thats the reason why i have better headlights at lower rpm. Was that you were saying sir? I am surprised that the ignition coil produces 15000 volts!! More doubts yet to come dear friends. My questions may be silly and simple to you people but it values to me a lot.

Ha ha, yes yes. Since we all love our bikes, and also have almost the same attitude, it would be very sad if the website goes off!! Divided by distance, united by XBHP. What say??!!

----consecutive posts auto-merged-----

Ah, another one passion pro owner. Welcome to the forum sir. What is the current odometer reading of your bike?

Re: Hero Moto Splendor/Joy/CD-Dawn/Passion

Don't think like that. No question is a silly question. Ask whatever you want. No one is born intelligent, we've also went thru the same. I have also asked many ques when I was newbie.
We understand what every question means to you and for everyone.

This website had previously gone thru two shutdowns before..
That happens when they do maintenance/upgrade over time.
Our reaction was also same when it shuts last time on its 10th anniversary. We weren't able to post anything. But started again and that was a upgrade, they changed the whole view of the website.
